Publicly available groundwater data have been compiled to provide a common information base to inform environmental, resource development and regulatory decisions in the Adavale Basin region. This web service summarises salinity, water levels, resource size, potential aquifer yield and surface water–groundwater interactions for the Lake Eyre Basin located within the Adavale Basin region.

<div>Geoscience Australia's Exploring for the Future Program (EFTF) is supporting regional and national-scale initiatives to address Australia’s hydrogeological challenges using an integrated geoscience systems approach. An important early step in the EFTF groundwater program focused on developing a national hydrogeological inventory of Australia’s major groundwater basins and fractured rock provinces. The inventory has its roots in the seminal 1987 Hydrogeology of Australia map, the first continental-scale map of groundwater systems and principal aquifers (Jacobson and Lau, 1987). Seeking to enhance and modernise the supporting information base for the national map, the inventory combines a curated selection of geospatial data attributes supported by focused narrative on the geology and hydrogeology of each basin and fractured rock province.</div><div>&nbsp;</div><div>The national hydrogeological inventory has a broad range of benefits for Australian groundwater users, managers and policy makers. These include the provision of an updated knowledge base covering the hydrogeology and groundwater systems of the major hydrogeological provinces of the nation, as well as important contextual information. The extensive catalogue of knowledge contained in the inventory also enables an objective approach to identify and prioritise areas for further regional assessment.</div><div>&nbsp;</div><div>Based on analysis of data compiled for the national inventory, the Lake Eyre Basin in arid central Australia was the first region prioritised for more detailed hydrogeological assessment during EFTF. The integration of a variety of basin- to national-scale geoscience datasets enabled significant advances in geological and hydrogeological understanding and the development of a new geological model for the three main basin depo-centres, namely the Tirari and Callabonna Sub-basins, and the Cooper Creek Palaeovalley. The geological modelling has further supported a range of hydrogeological applications, including substantial improvements in the number of bores with aquifer attribution, as well as the first regional watertable map across the basin.

Publicly available groundwater data have been compiled to provide a common information base to inform environmental, resource development and regulatory decisions in the Cooper Basin region. This data guide gives examples of how these data can be used. The data package included with this data guide captures existing knowledge of Lake Eyre Basin aquifers in the Cooper Basin region and their properties, including salinity, water levels, resource size, potential aquifer yield and surface water interactions. The methods to derive these data for the Lake Eyre Basin aquifer in the Cooper Basin region are outlined in the associated metadata files. These are described in groundwater conceptual models (Gouramanis et al., 2023). The Lake Eyre Basin overlying the Cooper Basin includes one broadly defined aquifer that includes multiple aquifer systems that are defined as Cenozoic aquifers. Compiled data are assigned to these intervals and used to characterise groundwater systems at the basin scale. The data were compiled for a point-in-time to inform decisions on potential resource developments in the Basin. The available historical groundwater data can be used to assess the potential effects on groundwater. The data can also be used for other purposes, such as exploring unallocated groundwater resource potential. Data to January 2022 were used for this compilation.

This data guide gives examples of how these data can be used. The data package included with this data guide captures existing knowledge of Lake Eyre Basin aquifers in the Galilee Basin region and their properties, including salinity, water levels, resource size, potential aquifer yield and indicators of surface water interactions. The methods used to derive these data for the Lake Eyre Basin aquifer in the Galilee Basin region are outlined in the associated metadata files. These are described in groundwater conceptualisation models (Hostetler et al., 2023). The Lake Eyre Basin overlying the Galilee Basin includes one broadly defined aquifer that includes multiple aquifer systems that are defined as Cenozoic aquifers. Compiled data was assigned to this interval and were used to characterise groundwater systems at the basin scale. The data are compiled for a point-in-time to inform decisions on resource development activities Basin. The available historical groundwater data can be used to assess the potential effects on groundwater for different development scenarios. The data can also be used for other purposes, such as exploring unallocated groundwater resource potential. Data to January 2022 are used for this compilation.
